T 0- all whom it may concern:

Be it known that I, Hi0 P. EiLnRs, acitizen of the United States, and aresident of New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in BoolePage-Recording Devices, of which the fol- The invention relates torecording devices for recording the number of the page at which readerceases reading a book and to which page he wished to at once open toresume his reading in subsequently taking up the book again for reading.

The objects of the invention will be set forth hereinafter in part, andwill in part be obvious to those skilled in the art.

The invention consists in the novel parts, construmiions,- arrangements,combinations and hnprovements, herein shown and described.

The accompanying drawings, referred to herein, and forming" a parthereof, illustrate one embodiment of the invention, the same serving;-in connection with the description herein to explain the principles ofthe inven tion.

Of the drawingsz l igure 1 is an elevation of a book provided with thepage rccording device; Fig. 2 is a fragmentary section on the line A Eof Fig. 1, and upon an enlarged scale; Fig. 3 is a fragmentaryperspective View showing the lining sheet side of the book cover of 1;and Fig.

at is a ClGW corresponding to Fig. 3 showing a somewhat differentarrangement of parts.

Referring to the accompanying drawings and to the embodiment of theinvention therewith illustrated, 1 represents the side cover of book,and 2 the back of the book. The side of the cover may be consruded inany suit-able manner, but shown herein of a construction which is quiteusual in what are ordinarily termed cloth bound and leathenbound.booksof ordinary literature. That is, the side cover consists of severalmembers or parts, usually a piece of binders board having on the outsidethereof the exterior leather or cloth cover folded over the bindersboard at the edges, and pasted or otherwise attached to side cover isusually pasted or otherwise attached on the inside of the side cover andover the folded over edges of the leather or cloth, thus making the workcomplete and slightly. In Fig. 2 the .sheet of binders board isindicated by 3, and the external cloth or leather by 4 folded over andattached to the inside of the sheet 3 of binders board at The liningsheet is indicated by the reference numeral 6. Located between two ofsaid cover members are a plurality of movable members, each hearing aseries of numerals, one of the cover members being apertured to permitsimultaneous observation of one numeral on. each of said movablemembers, so that they may be read together to indicate the number of thepage which the reader of the book wishes to record. The movable membersare shown as three disks 7, 8 and 9, rotatably fixed to the sheet 3 ofbinders board, and also, if desired, .to the outside cover 4:. The disksare shown attached by eyelts 10, each eyelet serving as an axis aboutwhich the disk rotates. Each disk is provided with the numerals ordigits in a circular series uponits side, and the disks are shown oneoverlapping the other to economize space.

In Figs. 1, 2 and 3 the numerals are arranged to be observed from theexterior of the book and in Fig. 4 they are arranged to be observed fromthe interior. In Figs. 1, 2 and 3, the side of the book is accordinglyapertured through the external cover- .ing 4 and through the .bindersboard 5, so as to expose a numeral on each of the disks. Three apertures11, 12 and 13 are shown formed by eyelets or rings set into the coverwith the flanges thereof turned over the parts l and 5, and eachaperture being, in register with the circle of numerals on thecorresponding disks 7, 8 or 9; each aperture being of a size to exposeone numeral only.

The edges of the disks 7, 8 and 9 project very slightly beyond the edgeof'the cover so that each of the disks may be turned bv the finger ofthe reader and yet isun likely to be disturbed accidentally by any othermeans. The lining sheet 6 covers the disk except for a small space wherethey project to be actuated by the readers finger, as will be clear fromFig. 2.

In 4 the page recording device is shown readable from the inside of thecover only and, if desired, may be constructed and arranged so that noevidences of it are discernible from the exterior of the book. In suchan arrangement the eyelet 10 may extend 0nly through the binders board3, the exterior cover; member 4 being continuous past it. The apertures11, 12 and 13 in such case are formed in the lining sheet 6 and, ofcourse, the numerals are on the opposite face of the disk from thearrangement shown in Figs. 1, 2 and 3. In Figs. 3 and t the body ofthe-book is indicated by 14 and the other cover by 15. In Figs. 1, 2 and4 the exposed or visible numerals on the disks are indicated by 16.

lV'th the device of the present invention,

the turning down of pages, the Withdrawing and re-inserting of a movableand project ing book mark, or the effort of endeavoring to charge thememory with a pa e number, are obviated. As the reader ceases reading,

he has merely to touch the edges of the disks to indicatethe page andwhen he wishes to resume reading a glance at the recorder instantlygives him his page number.

It will be understood that changes from the exact structure shown hereinmay be made within the scope of the accompanying claims, withoutdeparting from the principles of the invention.

What I do claim as my invention and desire to'secure by Letters Patent,is:

l. The combination with a book cover =com risin a luralit of covermembers attached together face to face, of a page indicator comprising aplurality of independently movable members movably mounted between twoof said cover members, each of said movable members having a pluralityof numerals thereon, and being accessible from the exterior of the coverso as to be moved as required, said cover being apertured to expose onenumeral on'each of said movable members to permit simultaneousobservation thereof, whereby they may be read as one number.

Q.'The combination with a book cover comprising a plurality of covermembers attached together face to face, of a page indicator comprising aplurality of rotatable disks located between two of said cover members,each of said disks having a plurality of numerals thereon, and each diskoverlapping another. of said disks, and being also accessible from theexterior of the cover so as to be moved as required, said cover beingapertured to expose one numeral on each of said movable disks to permitsimultaneous read, as one number.

v3. The combination with a book cover con' prising a plurality of covermembers,

, one ofsaid members being a lining sheet attached to the other of saidcover members, of a page indicator comprising a plurality ofindependently movable members located" between said lining sheet'and theother cover member, each of said movable members carrying a plurality ofnumerals thereon, one of said cover members being apertured to expose.and thus permit simultaneous ob serration of, one numeral on each ofsaid movable members, whereby said opposed numcrals may be read as onenumber.

a The combination with" a book cover comprising a plurality of'covermembers, one of said members being a lining sheet; attached to the otherof said cover members, of a page-indicator comprising a plurality ofindependently movable members located between and movably mounted uponone of said cover members, each of said movable members having a.plurality of numerals thereon, one of said cover members being aperturedto expose and thus permit simultaneous observation of one numeral oneach of said movablemembers, whereby said exposed numerals may be readas one number.

5. The combination with a book cover comprisinga plurality of covermembers, one of said members being a lining sheet attached to the otherof said cover members, of a page indicator comprising a plurality ofrotatable members located between said cover members, and mounted uponone of said cover members, each ofsaid rotatable members having aplurality of numerals thereon, one of said cover members being aperturedto expose, and thus permit simultaneous observation of, one numeral oneach of said rotatable members, whereby said exposed numerals may beread as one number.

6. The combination with a book cover comprising a plurality of covermembers, one of said cover members being a lining sheet attached to theother of said cover members, of a page indicator comprising a pluralityof rotatable numeral bearing disks located between said cover membersand to tatably mounted upon one of said cover members, the edge of eachdisk projecting beyond the edge of the cover, one of said cover membersbeing apertured to expose and thus permit simultaneous reading of onenumeral on each of said disks, whereby said exposed numerals may be readas oneof the cover, a plurality of orifices formed in "one of said covermembers, each orifice being of a size to expose a single numeral disk isexposed and may be simultaneously and being arranged in a row in linewith said dlsks, whereby one numeral'on each observed to be read as onenumber.

8. The combination with a book cover comprising a plurality of covermembers attached together face to face, of a page indicator comprising aplurality of independently movable men'lbers movably mounted between twoof Said cover members and overlapping one another, each of said IIIOV",able members having 'a plurality of nunier al s thereon, and beingaccessible from the exterior of the cover so as to be moved as required,said cover having a plurality of.

apertures, each being of a size to expose one numeral on each of saidmovable members to permit simultaneous observationthereoir', whereby theapertures are brought relatively close together and the numerals on therespective members may be read as one number.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing Witnesses.
